DESCRIPTION
UNE EN ISO 12999-2:2021
This part of ISO 12999 specifies the uncertainty of sound absorption coefficients and equivalent sound absorption areas measured according to ISO 354:2003, the practical and weighted sound absorption coefficients according to ISO 11654 and the single number rating according to EN 1793-1. Furthermore, the use of uncertainties in reporting measured or weighted absorption coefficients is explained.
